Embodiment
Fig. 1 shows the plan view according to an embodiment of coupling 1 of the present invention.Coupling is by a sheet material integral molding, and wherein in an illustrated embodiment, external frame cuts out from the thick flat sheet of 2mm by process for stamping.Coupling 1 comprises 1.11 to 1.16 and six contact pin 1.31 to 1.36 of six primary elements.Between primary element 1.11 to 1.16, also be provided with six join domains 1.21 to 1.26.Contact pin 1.31 to 1.36 strides across length t and correspondingly is molded on the join domain 1.21 to 1.26.That is to say that the length of the join domain of contact pin 1.31 to 1.36 on join domain 1.21 to 1.26 is t.Although length t only illustrates one in Fig. 1, this geometrical relationship is applicable to all join domains 1.21 to 1.26 or contact pin 1.31 to 1.36.Just purpose does not for the sake of simplicity just provide size to all suitable length.In Fig. 1, exemplarily given prominence to join domain 1.21 with oval-shaped dotted line.
Shown coupling 1 is with respect to central point M center symmetry.According to Fig. 1, primary element 1.11 to 1.16, contact pin 1.31 to 1.36 and join domain 1.21 to 1.26 are correspondingly respectively with respect to central point M center symmetric arrangement.In addition, primary element 1.11 to 1.16 is arranged closelyer than contact pin 1.31 to 1.36 decentre point M.The symmetrical mode of execution of coupling 1 can make the distortion homogenization of coupling 1 when being furnished with the angle measurement unit work of this coupling for, and this finally also helps the measurement precision of angle measurement unit.
Coupling 1 has relatively large clean inner diameter d.In the present embodiment, this clean inner diameter d is the diameter of a circle around the minimum of central point M contact coupling 1 interior profile.Correspondingly, outer diameter D is the maximum diameter of a circle around central point M contact coupling 1 external frame.Clean inner diameter d and outer diameter D are the decisive numerical value of the required structure space of coupling 1 or angle measurement unit.In the present embodiment, ratio d/D is about 73%.
To be called axially perpendicular to the draw direction on plane of Fig. 1 below.Correspondingly, radially be meant the direction of outwards pointing to from central point M.At last, tangentially be meant perpendicular to radial and axial direction.
In further describing, can with the shape description of primary element 1.11 to 1.16 triangle, two minor face is positioned at the outside with respect to central point M.Long limit is orientated tangentially (from the center on long limit) respectively.In addition, primary element 1.11 to 1.16 also has radial width r, R, and it is reducing on the direction of join domain 1.21 to 1.26.In other words be exactly, the geometrical shape of primary element 1.11 to 1.16 is so to constitute, and diametrically promptly, its width r, R are along with far away more and increase from the distance of join domain 1.21 to 1.26.By this geometric orientation or formation, primary element 1.11 to 1.16 has bending rigidity for tangential force and radial force.
In addition, primary element 1.11 to 1.16 with respect to one radial finger this intersection point by two minor faces, the imagination to the straight line symmetry.
In six contact pin 1.31 to 1.36 each all has two at the circumferencial direction supporting point 1.311 to 1.362 of distance T each other.Supporting point 1.311 to 1.362 is designed to have respectively the square area of a perforate.In order to make contact pin 1.31 to 1.36 also can be flexible when being loaded torsion, and contact pin 1.31 to 1.36 is designed to relative narrower and longer, and is also slotted.Groove and hole all are carved in the sheet material by laser means.Because contact pin 1.31 to 1.36 is big apart from T and narrow radial width, contact pin 1.31 to 1.36 is axially upwards relative more flexible with the footpath.Especially contact pin 1.31 to 1.36 the narrowest place diametrically is narrower than the maximum radial width R of primary element 1.11 to 1.16.This performance has also obtained the support of the fluting make of contact pin 1.31 to 1.36.
Between two supporting points 1.311 to 1.362, wherein, join domain 1.21 to 1.26 formation contact pin 1.31 to 1.36 are connected with primary element 1.11 to 1.16 in the join domain 1.21 to 1.26 each in a circumferential direction.Join domain 1.21 to 1.26 plays the effect of similar solid joint.Constitute by the corresponding adaptive geometrical shapies of join domain 1.21 to 1.26, two adjacent contact pin 1.31 to 1.36 or primary element 1.11 to 1.16 are utilizing the relative movement possibility that obtains under the situation of elastic properties of materials to be essentially radially.Design this geometrical shape, make coupling 1 is being applied radially or during thrust load, high mechanical stress in join domain 1.21 to 1.26, occurring.For this reason, as shown in Figure 1, join domain 1.21 to 1.26 has minimum width x diametrically.That is to say that the material thickness that the footpath makes progress sharply reduces in join domain 1.21 to 1.26.That is to say that by this way, join domain 1.21 to 1.26 and contact pin 1.31 to 1.36 are configured, make them much more crooked easily than primary element 1.11 to 1.16.Easily sheathed is with respect to radially and/or thrust load.Thus, radially and/or thrust load cause distortion in join domain 1.21 to 1.26 and the contact pin 1.31 to 1.36.In other words be exactly that primary element 1.11 to 1.16 is around longitudinal axis with around radially the plane moment of inertia of (perpendicular to Fig. 1,4 or 5 drawing plane) axis will be much larger than the respective planes moment of inertia of join domain 1.21 to 1.26 and contact pin 1.31 to 1.36.For this reason, design primary element 1.11 to 1.16 makes it attenuate towards join domain 1.21 to 1.26, and its width r, R increase along with the distance from join domain 1.21 to 1.26 increases far diametrically in other words.
Especially in order advantageously to design the bending properties of coupling, the ratio T/t of chosen distance T and length t makes that it is 9 in this embodiment.For reaching identical purpose, ratio R/x of the minimum width x of the Extreme breadth R of primary element 1.11 to 1.16 and join domain 1.21 to 1.26 is about 3.5 at this.
On the other hand, coupling 1 according to the present invention is very antitorque, thereby makes can not cause distortion substantially when supporting point 1.311 to 1.362 is applied tangential force, and this is for determining that accurately the angular orientation is very important.
Fig. 2 shows the angle measurement unit with coupling 1 and the partial sectional view of surveying device thereof.Angle measurement unit has a bearing unit 3, and it comprises outer shroud 3.2 and can be with respect to the hollow shaft 3.1 of outer shroud 3.2 rotations as parts.According to Fig. 2, arrange rotatable hollow shaft 3.1, make it pass coupling 1 by clean inner diameter d.
On hollow shaft 3.1, one dial 5 is set with relatively rotating, angular divisions or angle index are arranged thereon by bonding nothing.On outer shroud 3.2, for example a scanning board 4 is arranged by bolt.Light source, luminous by condenser 11 with have the scanning sheet 12 of scale for LED10 here.Wherein, LED 10, condenser 11 and scanning sheet 12 belong to the part of fixing (not the rotating) of angle measurement unit.
On the contrary, dial 5 is fixed on the rotatable hollow shaft 3.1.Dial 5 can be modulated the light of injecting according to the angular orientation of hollow shaft 3.1 by its angle index.The light of modulating just is mapped on the photoelectric detector (not shown) of scanning board 4 then.So just produced photosignal, it contains the information relevant for hollow shaft 3.1 angular orientations.The signal that should produce by photovoltaic is continued to handle by the electronic device of scanning board 4.At last, the position signal that is continued to handle is exported to another instrument by lead 7 (Fig. 3), as the control gear of machinery.
Fig. 3 shows the exploded view of the angle measurement unit with coupling 1.For simple and clear purpose, do not write out the reference character of the member of all couplings 1 among Fig. 3.See also Fig. 1 at this.
Three contact pin 1.31,1.33,1.35 of coupling 1 connect with outer shroud 3.2.For this reason in the embodiment shown, at supporting point 1.311,1.312; 1.331,1.332; 1.351, inserting bolt in 1.352 the perforate, and screw in the internal thread of outer shroud 3.2.Like this, three contact pin 1.31,1.33,1.35 are at its six supporting points 1.311,1.312; 1.331,1.332; 1.351, be rigidly fixed on the bearing unit 3 on 1.352, especially be fixed on the outer shroud 3.2.
Other contact pin 1.32,1.34,1.36 is rigidly fixed on another member of angle measurement unit, is on the flange 2 here.For this reason, be supporting point 1.321,1.322; 1.341,1.342; 1.361,1.362 perforate is equipped with bolt, contact pin 1.32,1.34,1.36 correspondingly is rigidly fixed on the flange 2.That is to say, in the embodiment shown, adjacent contact pin 1.31 to 1.36 is rigidly fixed in respectively on another member, be rigidly fixed in respectively on outer shroud 3.2 and the flange 2 at this, wherein, though outer shroud 3.2 and flange 2 do not rotate when angle measurement unit is worked, they still can relatively move.Like this, the contact pin 1.31,1.33,1.35 that is connected with outer shroud 3.2 of coupling 1 and other three contact pin 1.32,1.34,1.36 of being fixed on the flange 2 are opposite each other with respect to central point.Then on flange 2, put a lid 6, and be connected with its bolt.
The axle rigidity that will measure can not had in the hollow shaft 3.1 that is installed in angle measurement unit by coupling 1, and flange 2 can fixedly be assemblied on the housing with relatively rotating, wherein, in the range of tolerable variance that allows, compensate concentricity.This means, in the rotary course of hollow shaft 3.1,, in join domain 1.21 to 1.26 and contact pin 1.31 to 1.36, both axially also bending motion radially occurring according in esse error.
Can vividly describe the function of coupling 1 by means of Fig. 4 and Fig. 5.These two accompanying drawings are made with simulator program.With Fig. 1 different be that in this simulation model, the primary element 1.11 ' to 1.16 ' of coupling 1 has the geometrical shape that is essentially rhombus.
Fig. 4 shows the view of the coupling under the state that does not radially add load, do not have to be out of shape thus.If but for example owing to concentricity makes coupling be subjected to radial force, so will be as occurring distortion illustrating with the exaggeration size among Fig. 5.Supporting point 1.321,1.322; 1.341,1.342; 1.361,1.362 be rigidly fixed on the same member.Concentricity by simulation has produced the relative movement of these parts with respect to another parts, is fixed with remaining supporting point 1.311,1.312 on described another parts; 1.331,1.332; 1.351,1.352.In Fig. 5, the direction of this relative movement in the drawing plane be for vertically upward, thereby make supporting point 1.321,1.322; 1.341,1.342; 1.361, relatively move on 1.362 directions of arrow shown in the figure.Show that now maximum distortion appears in join domain and the contact pin, especially in two join domains 1.22,1.25 and contact pin 1.32,1.35.Even in the distortion shown in the hypergeometric example very, in primary element 1.11 ' to 1.16 ', do not see any distortion yet.That is to say that join domain 1.21 to 1.26 and contact pin 1.31 to 1.36 are easy to be much more crooked than primary element 1.11 ' to 1.16 '.As shown in Figure 5, with common coupling different be, compare with unstress state, under deformation state, the angle between the adjacent primary element 1.11 ' to 1.16 ' has changed.Angle between the primary element 1.11 ' to 1.12 ' has increased, and promptly increases as follows, and promptly primary element 1.11 ' to 1.12 ' is similar to around the imagination point in join domain 1.22 and is swung.But coupling is still antitorque as a whole, wherein can compensating axial sum of errors radial concentric degree error.As mentioned above, it is complete plane that coupling is designed at this, and wherein, radial force and/or tangential force can not cause axial distortion.This performance helps improving stiffness in torsion in addition.
In second embodiment, also be 9 apart from the ratio of T and length t, and ratio R/x of the minimum width x of the Extreme breadth R of primary element 1.11 ' to 1.16 ' and join domain 1.21 to 1.26 is about 4.5.
As in the described coupling 1 in an embodiment, three contact pin 1.31,1.33,1.35 connect with outer shroud 3.2, and other contact pin 1.32,1.34,1.36 are fixed on the flange 2.That is to say, respectively the contact pin 1.31,1.33,1.35 that connects with same member; 1.32,1.34,1.36 be not orientation parallel to each other.For this reason, have individual contact pin 1.31 to 1.36 of 2n (n 〉=3) and/or primary element 1.11 to 1.16; 1.11 ' in the coupling 1 to 1.16 ', complicated deformation pattern can appear when imposed load.But by according to design proposal of the present invention, coupling 1 is still stiffness in torsion, and axially and the footpath upwards be flexible.But a fairly large number of contact pin 1.31 to 1.36 and/or primary element 1.11 to 1.16 as mentioned above; 1.11 ' advantage to 1.16 ' is to obtain bigger clean inner diameter d, thereby can obtain the big clear passage of hollow shaft 3.1.On the other hand, can also make the outer diameter D of coupling 1 and the Outside Dimensions of angle measurement unit keep less by this structure.
Although two members 2,3 that can not rotate (stator coupling) of the 1 connection angle measuring device of the coupling in the present embodiment, the present invention also comprises following angle measurement unit, and wherein corresponding coupling 1 is as the rotor coupling.In this case, coupling is rigidly fixed on two rotating parts, and wherein, these two rotating parts can relatively move equally.
